Subscription Event Responses

CPS-1492 - Getting issue details... STATUS

1. NCMP will be aware of the registered DMIs and the CMHandles registered to a given DMI
   1. Therefore will know how many DMIs to be waiting for a response from
   2. Wait for timeout before sending event outcome? (30s)

Subscription Event Outcome

1. NCMP is to collate Event Responses from DMI and send.
2. Wait for timeout,
   1. if all DMIs returned send full Event Outcome
   2. else partial event outcomes
